I dissagree. If you don't have threads, how do you connect your hydraulic lines, or brake lines together. They have some type of furral on each end of the hydraulic line, or brake line, called compression fittings, with threds. These threads are called National Pipe Thread, or short NPT. I have been using 1/2" steel water pipe, for all my hydraulic needs, instead of regular hydraulic line. If you over tighten steel hydraulic lines, they twist, and kink in, because of their thin walls. Steel 1/2" gavenized waterpipe has a much thicker wall, close to 1/4" thick. and are much more solid than the steel hydraulic lines. If the water pipe leakes at the joints, you can tighten it up more, without ever twisting it, or kinking it. Steel water pipe as far as I am concerned is alot safer to use. I have never blown a line made of galvinized water pipe yet, but have blown several steel hydraulic lines, even the rubber hydraulic lines. Also galvenized water pipe can withstand greater presures. You don't see steel hydraulic lines used for natural gas lines for your house, or for steam ligns in factories They use standard steal black pipe for that.

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
